The same name was previously assigned to a character in Grimm Brothers. The two actors had told the world about their unborn baby back in May. They have never stopped sharing their expectations.

A reliable source said the couple was so thrilled by the outcome. "They've both talked about this for awhile and are so excited," an insider said to Us. "Everyone is beyond thrilled for them."

Bilson had told Cosmopolitan magazine in May that she has always dreamt of being a mother. "I definitely have family on the brain," she said. "Having kids is something I want to see in my future—I hope."

The couple had hosted a baby shower party at their home in Los Angeles in August 31st. The duo had invited some of their old friends including siblings and former school mates.

Though everyone was expected to give Bilson a gift, the guests left her with beaded necklaces that were believed to keep her going during labor. "She will use the beads for strength during labor," a source disclosed to Us.
